DEV: Correct historical badge and user_badge index discrepancies (#10017)
Badge and user_badge tables were created using add_column index: true
When the migration was written, `index: true` was a no-op for non-reference columns
Since then, rails made it work 9a0d35e820
This migration adds the index to very old sites, so that we have a consistent state
